ALBERT S. ROSS, F DALLAS, TEXAS SLUG EJECTOR Application led August 20, 1928. Serial o. 300,645.

This invention relates to slug ejectors for coin actuated money changers, vending ma chines and the like, and has for its general object the provision of certain new and useful improvements on the slug ejector covered by my pending application for Letters Patent of the United States filed on the 22nd day ofAAugust, 1927, Serial No. 214,515.

One specific object of the invention is to 1o provide new and useful fraud preventive means to eject all slugs which are magnetic, too light, or too heavy, said means being adjustable.

Other objects will appear in the following specification.

In the accompanying drawings,illustrating the preferred embodiment of the invention, Fig. 1 is a sectional rear elevation of the slug ej ector, on the line 1--1 of Fig. 2; Fig. 2, a sectional side elevation on the line 2-2 of Fig. 1; and Fig. 3, a sectional front elevation on the line 3-3 of Fig. 2.

The slug ejector may be enclosed within a suitable casing 1 having a-front wall 2 and a rear wall 3, the operative parts thereof being mounted upon the rear plate 4. -The rear plate 4 and the front plate 5 are spaced apart, as shown.

The deposit slot, through which operating 3o coins may be inserted, is indicated at 6, and it communicates with the entrance passageway 7 defined by the plates 4 and 5 and the plate spacing guide members 8. Below the passageway 7 the coin selecting beam 9 is pivotally mounted on the front side of the plate 4,

and below said beam the pin 10 divides the coin passageway 11 and the slug passageway 12. The slug passageway may lead to a suitable tray (not shown) on the outside of the machine. Passageway 11 may be adapted to direct operating coins to the coin actuated money changer, vending machine, or other device with which the slug ejector is used.

'Elements corresponding generally to the plication above identified. The operation libreof will briefly be described.

'When a coin 14 of the proper denomination is inserted in the deposit slot 6 it will roll elements just described are disclosed in my" downwardly thrcugh'the passageway 7 and fall substantially upon the pivot 9"d1 of the coin selecting beam 9 and roll to the right on the inclined upper edge 9b, slowly rotating said beam into the predetermined position indicated by the dotted lines 9, whereupon it rolls 55 off said beam. The position referred to is such with respect to the pin 10 that the coin 14 falls to the right of said pin and passes through the coin passageway 11 to be thereby directed to the coin-actuated machine.

Should a slug 13, heavier than a coin of the proper denomination be inserted, it too will fall upon the pivot 9a of the coin selecting beam 9, and roll to the right on the inclined upper edge 9", rapidly rotating the beam into the predetermined position indicated by the dotted lines 9d whereupon it will' roll off said beam. This position of the beam is such with respect to the pin 10 that the slug 13 falls to the left of said pin and into the slug passageway 12 through which it is ejected tothe tray (not shown).

Now the mechanism constituting the preferred embodiment of the present invention includes new and improved 'adjustable means to control the selection of coins by the beam 9. It will be obvious that rotation of the beam 9 in a clockwise direction on its pivot 9a will be dependent on the'weight of the coin and the lever arm, that is, approximately the distance between the pivot 9a and the point of contact of the coin with, the edge 9". And so, to rotate said beam, la light coin must roll a much greater distance to the right on said edge than must a heavy coin. To limit the movement of the coin to the right on said edge, I provide the stop member 15 (this stop member 1s a magnet, but its function as a stop member is not dependent upon its magnetic properties). The stop member is adjustably held on the front side of the plate 4 by the bolt 16 fitting in the slot 17 in said plate. It may, therefore, be moved to th'e left to stop all coins when they reach a predetermined distance from the pivot 9EL and thus prevent rotation of the beam by a coin of less thana predetermined weight. t may be moved to the right to permit said light coin to roll a much greater distance to the right from the pivot 9a before stopping it, so that. said light coin will rotate said beam. The slug ejector may be tested before use, and if it is found that slugs slightly lighter than coins of the proper denomination rotate said beam 9 and nd their way into the coin passageway, the stop member 15 may be moved to the left to prevent such rotation. If it should be found that coins of t-he proper denomination are unable to rotate the beam 9, the stop member 15 may be moved to the right to permit such rotation.

Referring now to the entrance passageway b locklng means adapted to prevent the insert1on of coins during the detention of a light slug. It is preferably in the form of a lever 17 pivoted at 17 c on the rear side of the plate 4, the upper end 17a of said lever extending through the arcuate slot 18 in the plate 4 and communicating with the entrance passageway 7; the lower end 17 1 thereof extending trough the arcuate slot 19 in the plate 4 into t e 9b o coin selecting beam 9. The weight 2O normally holds the blocking lever 17 in the position shown by the solid lines. Light coins or slugs rolling to the right on the edge 9b strike the lower end 17b of said lever and move it to the right, so that said lever assumes the position shown by the dotted lines, the upper end 17 thereof being moved into the entrance passageway 7 to direct coins and slugs into the discharge passageway 42 from whence they ass through the discharge slot 41 into a suita le tray (notshown) As above stated, the stop member 15 is a magnet. The beam 9 and the lever 17 are preferably made of metal other than iron, in

order that the magnet will not interfere with the movements thereof. Should a slug containing iron be inserted in the deposit slot 6, and roll down the edge 9b of the coin selecting beam 9, it will be attracted and held by the magnet 15. It will actuate the lever 1 as said lever, is actuated by light coins, as above described.

The slug ejector, therefore, includes means to arrest and detain magnetic slugs as well as slugs li hter than` coins of a predetermined weigt. N

To prevent the entrance of such slugs into the coin passageway 11 when they are released, (by means hereinafter described) I provide the gate 21 (see Fig. 3) pivoted at 21l to the front side of the plate 4 and having a slot 21b for the receptlon of the roller 22b carried by the spindle 22'L of the actuating rod 22 reciprocable on the rear side of the plate 4. The rotation of this gate 21 about its pivot 21a may be limited by suitable pins 23. The normal relative positions of the gate 21 and roller 22b are indicated by dotted lines 21 and 22. When the rod 22 is moved downwardly, the gate will close the coin passa eway 11, as shown by the solid lines.

eferring now to Fig. 1, it will be seen that path of the coins rolling down the edge the roller 22b carried by the rod 22 is also movable in the slot 24of trip lever 24 pivoted at 24b on the rear side of the plate 4. The trip lever 24 is pivotally connected to the link lever 25 (pivoted at 25a) on the front side of the plate 4 (see Fig. 3) by the bolt 26, which is movable inthe opening 27 in the plate 4. And so the trip lever 24 and the coin, selecting beam 9 are operatively connected together by the link lever 25.

A release lever 29, pivoted at 2 9b on the rear side of the plate 4, is normally in the position shown by Fig. 1.

The operation of the releasing mechanism just referred to is as follows.

Assuming that a light or magnetic-slug is being detained by the means above described, the entrance passa eway 7 is blocked by the en'd 17 1 of the bloclgring lever 17, and the rod 22 is in its normal position 22. Now the rod 22 may either constitute, or be operatively connected to, the actuating member of the machine with which the slug ejector is used; and so when an attempt is made to operate the machine, the rod 22 is moved downwardly and assumes first the position shown by the solid lines. When the member 22 is moved to this position it closes the gate 21 as above described, so that the detained slug when released cannot pass into the coin passageway 11. The upper and of said rod has a finger 22 which has been brought into engagement with the shoulder 29a of the releasing lever 29. And the roller 22b has been brought to bear against the trip lever 24 at the end of its slot 24".

When the rod 22 is moved further down- 1 ward, it will not change the closed position of the gate 21 (Fig. 3) but it will rock trip lever 24 (Fig. 1) on its pivot 24b 1n an anticlockwise direction, whereby the bolt 26 will be moved upwardly to rock the link lever 25 (Fig. 3). And the link lever25 will rock the beam 9. And the finger 22c of the rod 22 will ride downwardly upon the inclined surface of the shoulder 29a of releasin lever 29, thereby rocking said lever in a cloc se d1- rection on its pivot 30, so that the upper end thereof quickly moves the lower end of blocking lever 17 into' engagement with the detained slug, whereby said slug is kicked away v Y30 (Fig. 1) pivotally mounted at 30 upon the 'arm 30" of the member 30 and to the support 36, serves to hold the'member 30 against the inner endA of the set screw and so the disposition of the pin may be changed to the right or left (Fig. 1) by screwing the set screw 37 inwardly or outwardly, respectively. l

As suggested at the outset, the passage of coins and lslugs into the coin and slug passageways, respectively, will be dependent on the relative positions of the beam 9 and pin 10 when the coin or slug falls from said beam. j.

The adjusting means for the pin 10, just described, may, of course, be made in various ways. So also may the other elements of the preferred embodiment hereinabove described. It is to be understood therefore, that the hereinafter appearing claims are not limited to the device shown by the drawings.
